Sell photos. If you have a decent camera and a good sense of light, color, and composition, you can take and sell stock photos – i.e. nondescript images that lend themselves to many applications and are commonly used to illustrate online articles or products – with minimal effort. Stock photos of locations (a fire hydrant, a bare wall near an interesting tree, or anything you might find as a default background image on your computer) are easier to take, but stock photos of people (i.e. people arguing, people kissing, people laughing) usually sell for more, as they have more uses and require the written legal consent of your subjects. Hunt for a reputable stock photo dealer or database that will pay you fairly before signing on with anyone.

Are you seeing the possibilities here? Think about what book, or series of books you could write to help people in your field of expertise?

Great list! I have another to consider that I personally have 35+ years experience providing. Clean up litter outside commercial properties on foot using inexpensive hand tools. It’s almost as easy to do as going for a walk! I started doing this as a side gig in 1981 and soon grew it into a profitable full-time business. I share my experience in my book, Cleanlots.

Just a few years ago, I never thought I would be staff writing, and I never even thought about it. But once I began, I really started to enjoy it. I really love to write (yes, I do realize that I’m not the best and I probably should proofread more, but I do like to talk), and writing for different blogs was fun for me. How are people supposed to know that you are looking for a freelance writing position?

Daily Surveys can be taken one or more times per day. This is indicated in the survey description. Other targeted surveys can be taken as you see them. Be sure to complete these when you see them.

Start a small business. Being passionate usually translates to a superior product and better service, which is especially sought after in the age of the anonymous, 1-minute online review. Worried that there isn’t a market for your interests? The fact is that though you may not personally know many people who want what you have to offer, thanks to the internet, there’s a huge market for niche-products (pigeon diapers, chainmail wedding dresses, you name it)… and you might just end up being a trend-setter. To create an online store, you can either make your own website or, if don’t want to self-host, you can sell on eBay or a similar site.

City-dwellers often don’t use their cars for days or weeks at a time. That idle time can translate to money with services like Getaround and Turo, which let you rent out your car by the hour or day.

Just be sure you talk to your insurance provider before signing up to make sure that you don’t run afoul of the policy.

I found a most profitable ways is simply search an idea around on the net and select few that really be able to implement as offline business.

And a very sad thing about that was so rare that programs give real value to people. And not few were a scam scheme.

Start analyzing your decisions from the perspective of a firm. In economics, a firm's goal is simply to maximize profit. Well-run firms spend money only if they can expect to make more money from their investment, and they allocate their resources to the most profitable use. You're not a firm, of course, and you have other considerations, but if you make the majority of your time and money decisions by choosing the options that promise the highest return on investment, you'll likely earn more money, and that's good news for your shareholders (you and your family).
ebay is a popular resource for selling various used and unwanted items. However, there are specific sites for selling certain used items such as books, jewelry, wedding dresses, and electronics where you may have greater success. Also, to maximize earnings, it's important to take a great photo of the item and write a compelling, honest description.
One should think about their skills, hobbies and basic daily habits as well. Do you like to cook? Be a personal cook or dinner parties. Baking? Make wedding cakes or cupcakes for weddings/special events. Do you enjoy cleaning? Trying going to banks/repo companies and ask if they are in need of a repo cleaner or market yourself as a all-around cleaner. Know how to mow a lawn? Get paid to do it in your neighborhood.
